I use several custom widgets in a folder which has in it the special manifest.json file, with the special line "type": "exb-web-extension-repo" I want to organize my custom widgets in a hierarchical folders tree, by their subject. Is this possible? If yes, will I need same manifest.json file not only at the top folder but also in each sub-folder? ... View more

Currently, EXB developer settings pane does not have Action Tab for coordinates widget and image widget. How do I "upgrade" those 2 widgets (after I copy and use them as custom widgets) to have Action Tab?   ... View more

I use 2 custom widgets, one is a copy of esri's original coordinates widget and the other is a copy of esri's original image widget. I can modify my copies as I wish. The original image widget has a built -in option to sense when the user clicks it, and I need that when the user clicks it, it will activate the "onLocateClick" in my custom coordinates widget. This is my first trial to make communication between 2 widgets in EXB I see that both widgets - coordinates and image, do noyt have the Trigger/Message actions in the development system... and I do not understand why... and I do not know how to enable them to use this widgets communication way. So, What I tried to do is:    I declared public object "_myApp" in client/dist/experience/index.html    and in my custom coordinates widget.tsx code,    I aded a line "_myApp.coordinates = Widget"    before its export line at the end of the file. What I gained is that my custom image widget have access to _myApp.coordinates but from this point I am stuck, since I have no access to the coordinates internal "onLocateClick" function. I am new to React, so help will be greatly appreciated ... View more

I made EXB multipage app with header and menu of the various tabs at the top, and I need that when the app loads, it will not display the header (hide it? or just not display it?). I attach screenshot of current left-top corner of my app In chrome debugger I saw that if I set "display:none" for class "header", it will hide it, but I need to do it from within the web app. - I assume this should be controlled in "componentDidMount" somewhere. - I assume that client\dist\widgets\common\menu is the relevant widget   that I need to copy into my custom widgets folder and change it accordingly. - I saw that inside this widget there is a component drawer-menu.tsx   which has inside it className='header' which is actually the element I want to "hide". I need help: 1. how to automatically not display the header when the app loads.     (Later I'll need a code in another widget to control if the header is displayed or not. ) 2. Could the virtual dom be searched to change display attribute of some class, or is this not the way to do it? ... View more

I develop on EXB 1.13 for 3D views. I am newbie to React, and it seems that I don't know how to use "useState" correctly within the widget, so even after values are "saved" by useState, they are null when reading them... I'll describe what I did, the I'll present my problems: I copied the original widget client\dist\widgets\arcgis\coordinates into my custom widgets folder and I use it from there. I modified that the display of x,y coordinates, zoom, scale etc. is updated "on the fly" as mouse moves. But I noticed that if I modify mouse wheel alone, the display is not updated"on the fly", until I move the mouse horizontally or vertically. In order that the display of zoom and scale will update "on the fly" as I change mouse wheel, I did the next modifications: 1. after the useState          const [currentJimuMapView, setCurrentJimuMapView] = useState(null)      I added one more useState:          const [lastMousePointAsScreenCoordinates, setLastMousePointAsScreenCoordinates] = useState(null) 2. In function "const onMouseMove", since  threeDPoint is object with x,y, I added:      setLastMousePointAsScreenCoordinates(threeDPoint) 3. In function "const onActiveViewChange"     I added next code:     // When extent changes, update the display of x,y location, zoom, etc.     reactiveUtils.watch(() => view?.extent, async () => {         if (!view?.basemapView) return //since I use 3D sceneView         if (lastMousePointAsScreenCoordinates) {             const pointAsMapCoordinates = view.toMap(lastMousePointAsScreenCoordinates)             await displayOnClient(pointAsMapCoordinates, lastMousePointAsScreenCoordinates)         }     }) }) 4. Please note that function "const onActiveViewChange" does setCurrentJimuMapView(jimuMapView)      yet, as I described in Problem_2, the saved value is being read as null... my problems: Problem_1. in (3), lastMousePointAsScreenCoordinates is null, though I saved it by useState... Problem_2. Even if I bypass the useState and set some correct value in "pointAsMapCoordinates",      still, at end of function "displayOnClient" there is the code:      const view = currentJimuMapView?.view      and here again a similar problem:      Though currentJimuMapView has been set by useState in function "const onActiveViewChange",       it is now null... To summarize - I see I don't yet grasp how to save/read correctly by "useState" in the widget? ... View more
